Vantage Point Technology (VPT), a subsidiary of Marathon Patent Group, sued Amazon, Apple, Box, Dropbox, Google, and SugarSync for alleged infringement of a networking patent. In six separate complaints, VPT accuses defendants’ cloud storage and back-up products of infringing a patent related to transmitting documents between a server and a computer (6,615,233). The patent-in-suit originated with an operating company, Intergraph Corporation, which assigned the patent to VPT in September 2013. It does not appear that the patent has been previously litigated.
